Air Handler Definition

Air handler is the one that circulates conditioned air throughout your indoor living space. It is often associated with your heating and cooling system because of the outdoor and indoor units.

The indoor unit is the air handler, and when this is matched with your heat pump, it will generally circulate both cool and hot air depending on the season.

With properly sized air handlers, you will get the right amount of clean, comfortable air all year round. Air handlers add significant contributions when it comes to the overall efficiency of your system.

How efficient your air handler is, determines the work your outdoor unit has to do to make sure your indoor spaces are comfortable.

What Does It Do Exactly?

Depending on the design of your building, an air handler works in different ways. But overall, it is the principal indoor component of your heat pump system. When it is appropriately matched with your heat pump’s right capacity, it will deliver an efficient conditioned air through your home’s ductwork.

Air handlers are designed to be one component of a multi-part system. It is why you need to make sure your air handler and condenser are appropriately matched. It is not a matter of “what does an air handler do,” but it should be “how will an air handler make your entire HVAC system work better.”

As expected, given the fact of the name itself, the air handling unit moves the air around. Without the air handling unit’s blower motor and fan, many HVAC systems have no other way to keep cool or warm air circulating throughout your living space. It is the most crucial role for an air handler to perform. Think about getting an air handler because it is a major consideration.

It Does Heat Transfer

Mosty of air handling units is compatible with an evaporator coil. It means that they can pass heat to an exterior condenser as a part of the air conditioning system. If you paired an air handling unit to an energy sufficient heat pump, the unit could put the heat back into the house for winter weather.

It Does Dehumidification

Most air conditioner units can dehumidify your living areas as part of its normal operating cycle. With an air handler, you will be able to improve the dehumidification process using a variable speed or multi-speed fan. It is essential, especially if you live in a humid region.

When the parts inside the air handler are worn out or defected, it will prevent it from regulating the temperature and dispersal of the indoor air in our living area.

Air handler issues that impact your HVAC system’s performance may include a faulty blower motor. As a result, it will not circulate cool air properly or draws excess power to its job.

Some evaporator coils covered in debris can limit the overall system’s capacity to exchange hear. Dirty filters can also prevent air from flowing through the system.

Air Handler Maintenance

It is known that older components of a central air system do not perform the same well as the newly released ones. Air handlers lose their effectiveness, and older models do not have advanced technology compared to the new ones.

When you upgrade your home’s air handler, it will enhance your HVAC systems to perform and deliver cool comfort to your home. Not mentioning that they also help in keeping your energy consumption at a minimum cost.
